Last week, we celebrated World Environment Day with activities across our four sites in Africa. In Ghana, our Edikan team marked the occasion with a week of learning and action in local host communities, extending the theme of “Climate Action” from classrooms to the mine site. Inter-school environmental quiz competitions strengthened students’ knowledge on environmental sustainability, climate change, biodiversity conservation, sanitation, and responsible resource management. Winners from each zone advanced to a grand finale held on June 5 at Dunkwa Radio Visa, where Nkotumso Roman Catholic School emerged overall champion. Our Nyanzaga team in Tanzania held community-led environmental awareness sessions, tree planting and waste‑collection activities in Nyabila, along with a programme at Sotta East Primary School that included tree planting, awareness education, and the handover of watering cans, buckets, and waste bins supported by students, teachers, local leaders, district representatives and project staff. At Yaouré and Sissingué in Côte d’Ivoire, teams marked the day with tree planting activities in local communities, bringing together community leaders, school representatives and project staff.🌱

It was wonderful to welcome PMGL Board Chairman Ehunuabobrim Prah Agyensiam VI, paramount chief of Owirenkyi Traditional area in Ghana back to the communities surrounding our Yaouré Gold Mine in Côte d'Ivoire. 🤝 Joined by PMGL CEO Daniel Egya-Mensah and Yaouré Community Manager Kone Adama, the Board Chairman met with traditional leaders and community representatives from five local villages — reconnecting with many he had visited a couple of years ago and hearing firsthand how priorities and progress have evolved since. Discussions focused on what matters most to these communities: local development, employment pathways for young people, vocational training, and access to clean water and improved sanitation. One of the strengths of operating across multiple countries is the ability to draw on shared experience — what works in one community can inform and inspire what's possible in another. That cross-country perspective was very much part of the conversation. Ehunuabobrim Prah Agyensaim VI thanked the traditional leaders and community members for their continued openness and dialogue, and reaffirmed Perseus's long-term commitment to the communities that are home to our operations. $PRU

Happy World Environment Day! 🌍 At Perseus, responsible mining means protecting the environments where we operate — from protecting biodiversity and water stewardship and land rehabilitation to actively managing our impacts and creating lasting positive environmental outcomes. As a multi-mine gold producer across Africa, we are committed to good environmental practice at every stage of our operations. More to come from our sites over the coming week! 🌿 $PRU

Perseus continues to support and prioritise education-focused initiatives within the communities surrounding our portfolio of African gold projects. In April, Perseus Mining (Ghana) Limited Company commissioned a new, fully furnished 120 bed girls’ dormitory at the Ayanfuri Senior High School, located nearby our Edikan Gold Mine. For many years students at the school faced limited boarding capacity, overcrowded facilities, and for those unable to secure accommodation, the daily challenge of long commutes. The newly built facility includes 40 bunk beds, a toilet block, nine shower rooms, janitor and basement storerooms, and a 10,000 litre elevated concrete water tank supplied by a newly drilled and mechanised borehole. Safe and secure accommodation plays an important role in supporting girls to remain in school, pursue their ambitions, and build confidence as future leaders. Funded entirely through Perseus’s $PRU Edikan Trust Fund, the new dormitory marks one of the most significant investments in educational infrastructure that the Ayanfuri community has seen in recent memory. A commissioning ceremony held at the school brought together Perseus leadership, community leaders, and members of the school and local community to celebrate a project that has been years in the making (pictured 📸). Around the same time in Fobinso, also located nearby Edikan, we handed over a fully constructed kindergarten and primary school block including three classrooms, a kitchen and pantry, staff facilities, toilets and showers, furniture, teaching boards and an 85,000 litre elevated water tank with a filter system.

With heavy hearts, Perseus extends its deepest condolences to the family, friends, and colleagues of Mr. Leonard Mususa. Mr. Mususa served as a Board Member of Sotta Mining Corporation Limited since its incorporation in 2021, offering wisdom, guidance, and leadership that contributed greatly to the development of the Nyanzaga Gold Project, Perseus’s first mine in Tanzania, and its governance structure. He will be remembered for his humility, integrity, and lasting contribution to the organisations and people he served. May he rest in peace.

Our Nyanzaga Gold Project in Tanzania continues its push towards first gold in Q1 CY27. ✔️ The project recently eclipsed 6 million work hours LTI free ✔️ 4/7 CIL Tanks are now at full height ✔️ Mill installation OEM has mobilised and commenced mill install activities ✔️ The camp administration is now complete. We look forward to providing further updates in the months ahead as we advance towards first production at the project. Watch our latest construction update below 📺

Last week, Perseus brought together the people helping make the Nyanzaga Gold Project a reality – government officials, project partners, financiers, suppliers and the team on the ground – for a reception in Dar es Salaam to share progress and mark the milestone of being halfway through construction. Nyanzaga is a joint venture between Perseus Mining $PRU (80%) and the Government of Tanzania (20%), and will be our fourth operating mine on the African continent. Managing Director and CEO Craig Jones spoke to the strength of the project’s local foundations – 3,000 employees and contractors currently on site, 97% of whom are Tanzanian – and reaffirmed Perseus’s commitment to sustainability, local development, and long-term economic contribution to Tanzania. Craig reflected on what makes projects like this work: genuine alignment between government, community, business, and workforce and the trust that has to be built and maintained to get there.

Last week, Perseus met with the President of the United Republic of Tanzania, Her Excellency Dr Samia Suluhu Hassan, at the State House in Chamwino, Dodoma Region – a significant moment as Nyanzaga moves steadily towards production. The Perseus delegation included Independent Non-Executive Chairman Rick Menell, Managing Director and CEO Craig Jones and Chief Financial Officer Lee-Anne de Bruin, alongside Sotta Mining Board Member Professor Raphael Chibunda and Country Manager Isaac Lupokela. Discussions focused on the development of the Nyanzaga Gold Project and its contribution to Tanzania’s mining sector. The US$523 million mine is Tanzania’s first major new gold mine in nearly 20 years – and a significant long-term investment in the country’s economy. President Dr Samia Suluhu Hassan commended the scale of the investment and recognised its role in strengthening Tanzania’s mining sector and supporting national economic growth. Construction is progressing well, with first production expected in the first quarter of 2027. $PRU

We are delighted to welcome Wade Bickley to Perseus $PRU in the role of Chief Operating Officer, commencing 1 June 2026, further enhancing our leadership team. Wade has over 25 years of industry experience, with extensive expertise in gold and base metals operations across Australia, West Africa and Southern Africa. In recent years, he has held senior management and executive roles in the mining industry where he has led complex mining operations, processing production systems, major capital projects and operational turnarounds. He will lead our Operations across Africa at this pivotal time as we ramp up our underground operations at Yaouré and bring Nyanzaga into production — one of Africa's most significant new gold development projects. We look forward to him applying his extensive operational expertise to drive performance and outcomes across our portfolio. Welcome Wade!

The first underground production blast has been fired at Blika 1120 Ore Drive South at the CMA Underground Project, at our Yaouré Gold Mine in Côte d’Ivoire 💥 This is a key milestone and signals the continuation of the project’s ramp up toward steady-state production, scheduled for Q3 FY27. The CMA Underground mine is both the first mechanised underground mine in Côte d’Ivoire, and the first for Perseus. With investment in the CMA Underground project, Perseus continues to be a key partner in assisting to build skills in the Ivorian mining sector, and the start of underground ore production represents a significant milestone of the development of broader mining capability in the country. The first production blast is a defining moment for Perseus $PRU and Côte d’Ivoire, following many months of intensive underground development, drilling and infrastructure installation. We look forward to scaling up operations over the coming months, and we thank our site team and contractors for their hard work and dedication in helping us reach this exciting milestone.

Yesterday, our Chairman Rick Menell and Chief Corporate Affairs and Sustainability Officer, Melanie Pollard, attended the launch ceremony of the SIREXE - International Extractive and Energy Resources Exhibition 2026, held in Abidjan, under the patronage of H.E. Téné Birahima Ouattara, Minister of Defence and Vice Prime Minister, alongside the Minister of Mines, Petroleum and Energy, H.E. Mamadou Sangafowa Coulibaly. Under the theme “Extractive and energy industries: what infrastructure is needed to support economic development in Africa?”, the initiative reflects Côte d’Ivoire’s ambition to position itself as a regional hub, supported by its Integrated Mineral and Energy Resources Policy and a strong focus on infrastructure-led growth. We were also inspired by H.E. Bogolo Kenewendo, Minister of Minerals and Energy of Botswana, who highlighted the importance of sustainability, strong governance and partnerships in shaping a resilient and responsible extractive sector. SIREXE continues to reinforce Côte d’Ivoire’s strategic role in advancing Africa’s extractive industries and regional collaboration. Perseus looks forward to supporting this fantastic event once again later this year. 📸: Perseus $PRU Chairman Rick Menell with Côte d'Ivoire’s Minister of Mines, Petroleum and Energy Mr. Mamadou Sangafowa-Coulibaly.

Perseus $PRU has acquired a relevant interest in 9.9% of the issued shares of Aurum Resources (ASX: $AUE) via participation in the Aurum equity raising announced today. Aurum is an emerging mineral development company listed on the ASX. Aurum’s key asset is the Boundiali Gold Project, a pre-development and pre-study gold project located in the North of Côte d’Ivoire, West Africa. The Boundiali Gold Project has a reported Ore Resource of 100Mt @ 1.0g/t Au for 3.0Moz of gold. The Boundiali Gold Project is located to the south and along strike of Perseus’s Sissingué gold mine, which has been in operation since January 2018 and the processing hub for ore from Fimbiasso and more recently the Bagoé satellite deposits. The Boundiali’s northern most tenements are adjacent to the Company’s active mining area at Bagoé. Our Managing Director and CEO Craig Jones said: “The Aurum team have done an excellent job assembling a highly prospective tenement package and building a significant resource base at a relatively low cost. The location of their discoveries presents potential future synergies and Perseus is pleased to be able to support Aurum in developing the project. For a total cost of A$23.69M, the Aurum Share Acquisition provides a compelling opportunity to fast-track value creation in the region.”

As part of Perseus’s commitment to social responsibility, we actively support the local communities surrounding our projects in various meaningful ways. During Ramadan, we donated 700 x 10kg bags of sugar to the Ababda Melikab tribe, located in the vicinity of the Meyas Sand Gold Project in Sudan. The initiative aimed to alleviate economic hardship during the holy month, a time of fasting and reflection. Community members expressed their gratitude for the timely support provided during a period when sugar consumption is important for families who break their fast at sunset, allowing them to prepare traditional meals and desserts that are an integral part of their cultural and religious practices. Today, we wish a joyful Eid Mubarak to all those celebrating the end of Ramadan. May this time of reflection, gratitude and togetherness bring renewed energy for the months ahead. 🌙 📸 Pictured: Bags of sugar being distributed to local families. $PRU

Perseus has signed a Share Purchase Agreement to sell its 70% group interest in the Meyas Sand Project located in Sudan to Hong Kong Matrix Golden Fortune Mining Limited, a wholly owned subsidiary of Matrix Resources, for a cash consideration of US$260M. The purchase price comprises a US$10M deposit received on signing of the SPA and US$250M payable on completion of the transaction which is to occur on 22 April 2026. Proceeds will further strengthen Perseus's superior balance sheet along with consideration of additional capital returns to shareholders. Our CEO Craig Jones said: “Perseus maintains the view that the Meyas Sand Gold Project is a high quality gold project. A strategic review of Meyas Sand was undertaken as a result of the protracted armed conflict in Sudan and its impact on Perseus’s ability to progress the development at suitable scale. The sale represents an important step for Perseus in its portfolio optimisation and allows allocation of resources to core assets and its growth strategy. Matrix Group is a proven development partner with a vision for the Meyas Sand Gold Project that aligns with the development goals of Sudan.” Read more: loom.ly/JMeIz6M $PRU
